Imaging Interfacial Electric Fields on Ultrafast Timescales (Final Report)
The goal of this project is to dynamically probe interfacial electric fields on ultrafast timescales and sub-micron length scales. The proposed method could be applied to a variety of heterointerfaces, with particular emphasis on interfaces involving colloidal quantum dots. The primary objective is development of an ultrafast nonlinear optical imaging technique with this capability. A secondary objective is obtaining new insights into excited state charge carrier dynamics in colloidal quantum dot solids and at quantum dot interfaces. Research activities involve validation of the technical approach, construction of the microscope, and synthesis and characterization of materials to be studied using the instrument.
